opencode stuck to run

[PhantomYdn]

Description

Today I have implemented custom command. And after that opencode stopped to run. When run like this opencode --print-logs --log-level DEBUG it shows only this:

INFO  2026-01-14T06:38:18 +378ms service=default version=1.1.10 args=["--print-logs","--log-level","DEBUG","-c"] opencode
INFO  2026-01-14T06:38:18 +1ms service=config path=/Users/phantom/.config/opencode/config.json loading
INFO  2026-01-14T06:38:18 +0ms service=config path=/Users/phantom/.config/opencode/opencode.json loading
INFO  2026-01-14T06:38:18 +6ms service=config path=/Users/phantom/.config/opencode/opencode.jsonc loading

Only running opencode web helped to clarify the situation. In a browser I found the following:

{"name":"ConfigFrontmatterError","data":{"path":"/Users/phantom/.config/opencode/command/reflect.md","message":"Failed to parse YAML frontmatter: incomplete explicit mapping pair; a key node is missed; or followed by a non-tabulated empty line at line 2, column 39:\n     ... ption: End-of-session reflection: checklist items and documentat ... \n                                         ^"}}

Apprarantly problem was a character ":" at a command description. Seems that there are multiple things which worst to address:

• Proper handling of wrong YAML
• Proper logging such cases
• Potential repeating the case for other entities like agents and skills

Plugins

No response

OpenCode version

1.1.10

Steps to reproduce

1. Create a global command with using extra ":" at command description
2. Try to restart opencode
3. It just stuck without any messages
4. Enabling logging is not helping much

Feel free to ignore if none of these address your specific case.

@PhantomYdn how did you come up with
{"name":"ConfigFrontmatterError","data":{"path":"/Users/phantom/.config/opencode/command/reflect.md","message":"Failed to parse YAML frontmatter: incomplete explicit mapping pair; a key node is missed; or followed by a non-tabulated empty line at line 2, column 39:\n ... ption: End-of-session reflection: checklist items and documentat ... \n ^"}}
I'd like to debug my istance since it hungs as well
